The INA333AIDRGT is a low-power Precision Instrumentation Amplifier offers excellent accuracy. The versatile 3 op-amp design, small size and low power make it ideal for a wide range of portable applications. A single external resistor sets any gain from 1 to 1000. The INA333 is designed to use an industry-standard gain. The amplifier provides very low offset voltage (25μV, G>=100), excellent offset voltage drift (0.1μV/°C, G>=100) and high common-mode rejection (100dB at G>=10). It operates with power supplies as low as 1.8V (±0.9V) and quiescent current is only 50μA ideal for battery-operated systems. Using auto calibration techniques to ensure excellent precision over the extended industrial temperature range, the amplifier also offers exceptionally low noise density (50nV/√Hz) that extends down to dc.
